电力起爆在地質勘探的坑、井探中具有重要的意义。自从电力起爆推行以来,不仅保証了爆破作业的安全,而且提高了炮眼利用系数,并直接降低了工程成本。根据1957年7月份在542队坑探工程中观察的资料,由于电力起爆准爆率高且爆力集中,較火力起爆約提高炮眼利用系数9.9％,同时,降低單位进尺火藥消耗11％(见表1)。表1
Electricity detonation in the geological exploration of the pit, well exploration is of great significance. Since the initiation of electric detonation, not only the safety of blasting operation has been guaranteed, but also the hole utilization factor has been raised and the project cost has been directly reduced. According to the observation made in 542 team of pit exploration project in July 1957, due to the high detonation rate and concentration of explosive power, the detonation rate was increased by 9.9% compared with that of firepower, and the unit consumption of gunpowder was reduced by 11% at the same time (see Table 1).
